STORAGE MEANS FOR GASES AND THE LIKE.

No Drawing.

To all whom it may concern:

Be it known that I, EDOUARD ERNEST Pn'rrrrrnmzn, citizen of the French Republic, residing at Paris, 19 Rue Brunel, Seine, France, have invented certain new and useful Improvements in Storage Means for Gases and the like, of which the following is a specification.

This invention relates to the storage, in suitable vessels, of dissolved or compressed gases and of inflammable liquids, and it concerns more specially, but not exclusively, the storage, in suitable vessels or containers of dissolved acetylene.

It is known that, for such storage of certain dissolved or compressed gases, more particularly acetylene, and certain inflammable liquids, it is necessary to fill the container with a suitable porous material.

The porous materials henetofore proposed for this filling do not fulfill, when taken separately, the necessary conditions, namely: lightness, porosity, the elasticity, freedom from the formation of cracks, splits and zones of unequal absorption, ease of refilling and areduoed cost of manufacture.

The invention has for its purpose to rem edy the disadvantages of different porous materials utilized heretofore.

In carrying out my invention I utilized the spongy, fibrous materials which are called turfs in some European countries and which are called peats in the United States. I can utilize these peats containing all their constituents, or containing only a part of their constituents.

For constituting the porous material which must fill the bottleshaped vessel or container, I prefer to use said peat or turf, preferably fibrous turf. I prefer to use a peat or turf which has been extracted, or has been specially prepared. The peat or turf may be ground, or compressed into lumps, or made into turf-powder or turfwadding. If a fibrous peat or turf is used, then the fibres thereof can be mixed with other fibres or porous materials. As be- Application filed September 9, 1922. Serial No. 587,220.

to the substance which is called peat in the United States.

A suflicient quantity of the above mentioned material is used to completely fill the bottle-shaped container. The porous material is forced into the container by any suitable means so as to completely fill it and then the said material'can be saturated with acetone in which the acetylene can be dissolved.

This material has the following advantages:-

Particularly it has a comparatively small density.

It is very porous, because including an in- 06 finity of cells, and, consequently, capable of absorbing a great deal of liquid or gas.

It is very elastic, particularly the turf of the varieties known as fibrous turfs and yellow turfs, and its elasticity is such that, with a comparatively weak compression, no sinking is to be feared.

Its constitution is such that it is possible, by utilizing, for instance, ground turfs, to obtain into the bottle-shaped recipient an homogeneous whole without any risk 01f causing cracks, splits, and zones more felted the one than the other or of lesser absorption.

It enables an easy filling of the recipient.

Its cost of manufacture is comparatively very low.

As it is obvious, and as it has, besides, been already suggested, the invention is in no manner restricted to that of its modes of application, nor to that of the modes of realization of its various parts having been more specially indicated; it embraces, on the contrary, all the modifications thereof, including, of course, those wherein the turf, or the elements of turf, would be utilized in combination with one or more other appropriate porous materials.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A storage vessel for dissolved gases and the like having a mass of compressed elastic peat particles contained therein, the said particles forming a substantially uniform mass substantially free from any open ings or recesses.

2. A storage vessel for dissolved gases and the like having a mass of compressed 5 elastic peat particles contained therein,

the said particles forming a substantially uniform mass substantially free from any openings or recesses, the said peat being substantially free from any foreign substances and constituting an elastic compressed body of uniform elasticity and porosity.

In testimony whereof I hereunto affix my signature.
